Fully Softened and Residual Shear Strengths of Midra Shale
( Qatar Univesrity Press , 2020 , Conference)This paper presents a comparison of the fully softened shear strengths measured using the triaxial and torsional ring shear devices for a shale that possesses noticeably high plasticity and induration. The residual shear ... -
Influence of Aspect Ratio on the Bearing Capacity and Correlated Modulus of Subgrade Reaction for Shallow Foundations on Dense Sand
( Qatar Univesrity Press , 2020 , Conference)One of the most fundamental problems in the field of geotechnical engineering is the prediction of bearing capacity and settlement of shallow foundations on cohesion-less soil subjected to vertical central loading. The ... -
Geotechnical Aspects of Sub-Sea Tunnelling on the Musaimeer Pumping Station and Outfall Tunnel Project
( Qatar Univesrity Press , 2020 , Conference)Musaimeer outfall tunnel is one of the longest storm water tunnels in the world with a total length of 10.2 km. The tunnel is connected via a drop shaft to the main pump station. This system will accommodate surface and ... -
Treatment of Wastewater Using Reverse Osmosis for Irrigation Purposes
( Qatar Univesrity Press , 2020 , Conference)This work investigates the performance of reverse osmosis (RO) for the reclamation of treated sewage effluent (TSE) to be used as irrigation water for food crops. The feed water used in this study was a real sample of ... -
Impact of Ionic Strength on Colloid Retention in a Porous Media: A Micromodel Study
( Qatar Univesrity Press , 2020 , Conference)Release of deposited colloids in the soil porous media during two-phase flow poses potential health hazard due to the facilitated transport of contaminants towards groundwater reservoirs. Considerable uncertainties exist ... -
Utilizing Steel Slag in the Removal of Suspended Solids from Dewatered Construction Water
( Qatar Univesrity Press , 2020 , Conference)Construction dewatering is an operation used to remove shallow groundwater that infiltrates construction sites. After recovering this water from the construction sites, the water is either discharged to the sea, injected ... -
Predicted and Back-calculated Coefficients of Permeability of Randomly Fractured Rock Mass: A Case Study
